EMERGENCY-TIRE.

Specification of Letters Patent Application led January 27, 1908. SerialNo. 412,801.

To all whom 'it may concern.'

Be it known that I, Dn WITT NELSON, of Minneapolis, Hennepin county,Minnesota, have invented cert-ain new and useful Improvements inEmergency-Tires, of which the following is a specification.

My invention relates to emergency tires designed particularly forautomobile use and capable of being substituted for the ordinarypneumatic tire when it is rendered useless by a puncture or for anyother reason, to enable the driver of the machine to operate the carwithout the necessity of running on the wheel rim.

A further object is to provide an emergency tire capable of .applicationto any size and make of automobile wheel.

A further object is to provide a tire adapted to be separated and packedaway in a small compass.

A further object is to provide an emergency tire which can be easily andquickly applied to a wheel and as readily removed.

My invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed o-utin the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of a wheel with my emergency tire applied thereto,a portion of the tire being in section to illustrate the manner ofsecuring it to the wheel. Fig. 2 is a sectional view on the line m-m ofFig. 1. Fig. 3 is a detail sectional view illustrating the manner ofsecuring the sections or segments of the tire together. Fig. 4 is anenlarged detail view illustrating the manner of locking the tiresections on the wheel. Fig. 5 is a detail view of the metallic frame inwhich the tire proper is mounted. Fig. 6 is a sectional view on the lineg/-g/ of Fig. 4. Fig. 7 illustrates the manner of tilting the sectionslaterally to interlock them with one another.

In the drawing, 2 represents an automobile wheel having the usual rim 3in which the pneumatic tire is seated. This rim is usually metallic andof comparatively light weight and serious damage often results to it andthe wheel by running the machine with a tire removed. In my presentinvention I provide means whereby the wheel is rendered capable ofservice within a very short time after the pneumatic tire is removed.

curve of the tire sections.

In carrying out my invention I provide a series of skeleton metallicframes 4 curved to correspond t-o the periphery of a wheel andconsisting of side bars and cross bars 5 connecting them near the middleof the frames. At the ends cross plates G, 7 and 8 are provided whichmay be formed integrally with the side bars or not as preferred. To theplates 6 and 7 wooden fellies are secured by screws 9 that are countersunk into the fellies, recesses 10 being provided in the fellies toreceive the cro-ss bars 5. These fellies are uadapted to fit the rim ofthe wheel. Each of the plates 6 has an eye 11 formed thereon and a lug12, the lugs and eyes being oppositely arranged in the ad,- joiningsegments of the tire so that the eye of one segment will receive the lugof the contiguous segments, recesses 13 being formed in the ends of thefellies to allow the insertion of the eyes therein. In connecting thesegments of the tire together it is necessary to tilt them laterally asindicated in Fig. 7 so that the lug of one segment will enter its eye inthe opposite segment, and when the segments are united it will beimpossible for them to become accidentally separated as it will benecessary to tilt or partially rotate them before such separationcan'occur.

The metallic frames have flanges 14 formed thereon, the edges of whichare adapted to be turned inwardly to grip the base of the hard rubbertire sections 15 that are fit-ted within seats 16 provided between theflanges 14. These flanges will hold the hard rubber sections firmly inplace and prevent any possibility of their becoming detached from thefellies inclosed by them. At the same time this manner of securing thehard rubber t-ire sections allows them to be removed whenever it isnecessary to repair or replace any of the sections. v

The plates 8 are provided with holes 17, said plates being located inthe abutting ends of contiguous sections. A stud 18 having right andleft hand threads thereon extends through the holes 17 in said platesand into nuts 19 that are threaded to receive said stud, and have curvedsurfaces fitting correspondingly shaped seats 2O to allow the nuts torock and seat themselves and the stud to accommodate itself to the Abolt passing into rigid sockets and securing the tire sections togetherwould bind or cramp when Patented June 11, 1912.

provided with a coupling means.

the sections were drawn up and considerable strain would fall on the`bolt or stud while the wheel was in use. By providing the nuts with thecurved bearing surfaces I am able to draw the sections of the tiresnugly around the rim of the wheel without danger of cramping the studor throwing any unusual or unnecessary strain thereon. A disk 21 isformed on the stud having sockets 22 toreceive a pin and allow theoperator of the machine to turn the stud and draw the tire sectionstogether. The ends of the tire sections carrying the threaded stud arerecessed, as indicated in Fig. 4ito allow suiiicient room for theoperation of the disk and stud.

There may be any desired number of the tire sections according tothe-size of the wheel and `the space in which `itis desired to pack theparts when not in use.

The tire sections are interchangeable and are all alike except that twoof them are Itis not necessary therefore in assembling the tire to doany itting or adjusting as the sections may be easily coupled togetherwherever placed on the wheel, it being merely necessary to arrange thesections with` the coupling members contiguous to one another.

I claim as my invention l.` An emergency tire comprising tire sectionshaving acoupling, means at their ends,

said coupling means being connected bypartially rot-ating one of `saidsections, and means for drawing the coupled sections. together.

2. An emergency tire comprising skeleton metallic frames and woodenrimsections secured thereto, said frames having,

seats forfthe tire sections and couplings at their ends included withinthe circumference of said sections, wherebythe/abutting ends ofvthersections may be connected together, and means for clamping theVtire.

sections on a rim. I

3. An emergency tire comprising metallic frames having seats therein forsolid rubber sections, and flanges arranged to grip. said sections,wooden rims provided .ontA the opposite side of said frames from saidrubber tire sections and means fo'r'securing them to said frames, andcouplings provided `at tions and means for coupling them together,

and means for drawing the said sections around a wheel rim, said meanscomprising a stud having right and left hand threads thereon,l and burshaving curved surfaces loosely mounted in said tire sections and havingthreaded holes toreceive said stud.

6. An emergency tire comprising metallic frames having plates at oneendand couplings mounted thereon, plates at the oppositeends of said frameshaving holes there-y in, a stud having right and left hand threadsthereon tting loosely within the holes of adjoining sections, burshaving curved surfaces and threaded holes to receive said stud, andmeans for revolving said stud .to tighten said couplings and draw said.tire sections snugly around .the wheel rim.

7. An emergency tire consisting :of sections having frames and.- felliessecured thereto, and tread sections mounted in said frames, said fellieshaving recesses in their ends and coupling means foi uniting theabutting ends of adjoining sections, said.

coupling means being connected byfrotatiiig one of the sectionspartially to allow its coupling member to engage the memberof theothersection, and means fordrawing saidtire sections snugly around .thewheel rim.

In witness whereof, I have hereuntoset myhand this 24th day of January1908. Y
